I hope the video manages to show the problem well.
Ever since putting on a new chain, after my old one broke, my bike is a lot noisier. Of course I expect some sound from the chain but there seems to be this clicking/ rattling noise from the chain somewhere between the 2 pulleys and derailleur cage.
Would appreciate any help been sitting here trying to fix it for hours
Thanks 🙂
This sound is driving me nuts, what is it?!!?

If you just replaced your chain and nothing else your cassette is also probably worn.
Sounds like it might be the chain slightly rubbing against the derailleur guide, (near the pulley wheel) I’m not an expert by any means so don’t quote me on this
Your chain is routed incorrectly through your derailleur. It should sit on the other side of the tab. The sound you hear is the metal on metal grinding of the chain on the tab.
You have the chain feeding the wrong way between the two pulleys. Move the chain to the other side of the tab between the pulleys. The chain shouldn’t touch the tab– it should move in a direct line from pulley to pulley.
I had this same issue this weekend. The chain is routed wrong.
Reset the counter!
Who wants to be that OP still hasn’t figured out where the problem is?
If it makes you feel any better, I was a shop mechanic for 4 years, and I did this on my own bike recently.
Chain is running through the cage on the wrong side.
Routed wrong. The chain is rubbing on the cage. Should be on the other side.
You’d think they would add something that prevents the chain from moving if it’s threaded incorrectly between the jockey wheels. This problem reoccurs because threading the chain incorrectly still actually works – albeit annoyingly.
Ahh, another one falls victim. Don’t worry OP, we’ve all done it.
